Description Classic Update kits are designed for projects that require more circuits than would have been available in an original chassis harness. Each kit is designed to include all the basics needed to rewire a vehicle from headlight to tail light, and will accommodate popular add-on items such as electronic fuel injection, aftermarket gauges and common supporting modifications.  Updated ATC fuse panel and fuses, along with modern GXL wire throughout. Wire functions are labeled every 3 to 5 inches. Pre-built dash harness and our exclusive gauge cluster disconnect system for use with stock or aftermarket instruments. Engine and front light harness with extra-long leads for custom routing and updated engine and transmission combinations.  Six-way power accessory plug can be used as a convenient power source for aftermarket accessories. Dash light candelabra makes for simple inclusion of auxiliary gauges. Rear body wiring with extra-long leads allows for custom routing. Factory pass through grommet included. 175 amp mega fuse kit with 6 gauge charge cable to support a high output charging system and internally regulated alternator. Built-in headlight, fog light and horn relays. Original-replacement connectors, terminals and lamp sockets.  Steering column adapter kit can be used to mate with stock or aftermarket columns.
